Bollywood megastar Amitabh Bachchan, who will be seen in a film themed on caste-based reservations, says he doesn't believe in the caste system, has never faced any bias because of his caste and is proud that his father gave him a surname that doesn't denote any such thing

"If ever I have faced a rejection or a failure, it has been on the basis of my incapability to do something and never my caste," Amitabh, 68, told IANS in an interview.
